[1] Trinny Woodall and Susannah Constantine teamed up in 1994 to write Ready to Wear, a weekly style guide for the Daily Telegraph which ran for seven years.

They later became the co-founders of Ready2shop.com, a dot-com fashion advice business which ceased trading after running out of funding in November 2000, losing investors a reputed £10 million.

[4] They later gained their first chance at working on television when Granada Sky Broadcasting signed them up to host a daytime shopping show, also called Ready to Wear.

[5] After a makeover slot on Richard & Judy, Jane Root, the controller of BBC Two, signed them up even after their book Ready to Dress and their internet business Ready2shop.com had failed.

[8] The editor of ELLE, Sarah Bailey, has stated "You just don't expect posh girls to grab your tits, call your trousers 'too clitty' and use words like 'pussy pelmet' but they do.

[11] They have also given different celebrities makeovers which include Jeremy Clarkson, Lesley Joseph,[12] Jo Brand, Sophie Raworth and Ingrid Tarrant.

The first two series saw the pair helping couples with marital problems, where they gave them advice and fashion makeovers to try build confidence and ultimately aim to revive the relationships.

[29] The television advertisements featured them both trying to rob a Littlewoods designer warehouse, but their mission is ruined when Constantine becomes stuck in between the protective bars, prompting Woodall to utter "You and your curves", before they are taken away by security.

[32] Also in 2006, they launched their own underwear range; "Trinny and Susannah Magic Knickers" which are made of nylon, designed to flatten the tummy and buttocks and thighs so they appear slimmer and compact.

[33] On 16 October 2006, they appeared on NBC's The Today Show, giving makeovers to three women and promoted their book, Trinny & Susannah Take on America.

[34] In a poll of 3,000 people conducted by Radio Times, they were ranked as the ninth most terrifying celebrities on television, largely due to their use of direct and frank advice.

"[36] Their newly formatted series, Trinny and Susannah Undress the Nation, began to air on ITV in November 2007 and explored the major fashion problems in Britain.

[39] They announced a tour to New Zealand and Australia in 2007, where they made a series of public appearances at shopping malls owned by the Westfield Group in February and March 2008.

[40][41] During the tour, which included visits to Melbourne and Sydney, they performed live styling sessions and gave fashion advice to customers at the Westfield centres.

[43] Woodall and Constantine also appeared on The Morning Show hosted by Kylie Gillies and Larry Emdur, to give one of the viewers a complete makeover.

In a filmed stunt for their new show, The Great British Body, which was broadcast in June 2008 on ITV, Woodall and Constantine stripped naked with 300 others on a Sussex hillside to create a giant living sculpture.

"The cast consists of professional actors and standup comics, the dialogue is part-scripted, part-ad-libbed, and the overall effect is weirdly postmodern and surprisingly successful.

The biggest surprise of all is Trinny and Susannah's acting ability, which is astonishingly convincing, even though, as they cheerfully point out, they're only playing hyperbolised versions of themselves."

[50] (in Hebrew) In the end of March and the beginning of April 2011 Trinny and Susannah toured across Poland, doing makeover for women and men in the country's four biggest cities.

Alistair McGowan's Big Impression took to spoofing their personalities on What Not to Wear,[4] as did 2DTV who made cartoon versions of Woodall and Constantine giving Santa Claus a makeover, where they stripped him of his red suit and added a casual shirt and trousers.

Woodall and Constantine were similarly depicted in the comic Viz in a cartoon strip as being bullies that picked on children who wore NHS glasses and second-hand clothing.
